Abstract
The utility model discloses a peripheral dust suction hood and a dust collector provided with the peripheral dust suction hood. The peripheral dust suction hood comprises a hood body, wherein an air outlet is formed in the upper portion of the hood body, dust suction ports are formed in the lower portion of the hood body, the middle of the lower portion of the hood body is sealed, and the dust suction ports are distributed along the periphery of the lower portion of the hood body. Compared with a traditional dust suction hood, the peripheral dust suction hood has the advantages of carrying out dust suction at fixed points and being controllable in range. Due to the fact that the dust suction ports are centralized, the suction force of the dust suction ports is large, and dust and air can be led out. Due to the sufficient suction force, the consumed power is small with the same suction force, and the dust within the range of the dust suction ports can be fully absorbed. The structure is simple, and maintenance is convenient.
Description
Technical field
The utility model relates to a kind of peripheral dust shield and the dust catcher of peripheral dust shield is housed.
Background technology
All can produce a large amount of dust in a lot of fields such as weaving, mining, metallurgy, machining, affect the healthy of employee, so dedusting be particularly important.Dust shield is device commonly used in removing dust project, thereby it mainly causes certain negative pressure effectively the dust and the pernicious gas that produce in production process to be siphoned away by blower fan at cover mouthful, reaches the dust cleaning purpose.As shown in Figure 1, the band dust air of traditional dust shield is to suck from cover mouthful, and the dedusting area is large, and in the middle of causing covering mouth, suction is large, and peripheral suction is little, causes dedusting mouth suction to reduce, and affects dust removing effects, healthy unfavorable to the employee.And, due to the impact of air-flow, the air beyond dust shield mouth scope also can be sucked, cause energy consumption higher.
The utility model content
The technical problems to be solved in the utility model takes above-mentioned the deficiencies in the prior art, and a kind of adjustable point dust suction, suction is large, energy consumption is low peripheral dust shield are provided.
The technical solution adopted in the utility model is: a kind of peripheral dust shield, comprise that top has the cover body that gas outlet and bottom have suction port, and sealing in the middle of the bottom of described cover body, suction port is along the peripheral distribution of cover body bottom.
As the preferred technical scheme of the utility model, the cover body lower end is with inside
downwardsthe baffle plate tilted connects, and horizonal base plate is by the baffle plate lower end closed, and the angle that baffle plate and base plate form is greater than 110 degree, and suction port is uniformly distributed on baffle plate.
As the preferred technical scheme of the utility model, described suction port is rectangle or circle.
As the preferred technical scheme of the utility model, the angle that described baffle plate and base plate form is between 120 degree～150 degree.
As the preferred technical scheme of the utility model, the angle that described baffle plate and base plate form is 135 degree.
And the dust catcher that above-mentioned any peripheral dust shield is housed, the air entry of described dust catcher communicates with the gas outlet of peripheral dust shield.
The utility model is compared with traditional dust shield, has the following advantages:
1, fixed point dust suction, scope can be controlled;
2,, because suction port is more concentrated, so the suction of suction port is larger, band dust air can be drawn in the past;
3, because suction is more abundant, so the power that identical suction consumes is less;
4, the dust in the suction port scope can fully absorb;
5, simple in structure, easy to maintenance.
The accompanying drawing explanation

The structural representation that Fig. 2 is the peripheral dust shield of the utility model.
The lateral plan that Fig. 3 is Fig. 2.
The A that Fig. 4 is Fig. 2 is to view.

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
The specific embodiment
A kind of peripheral dust shield, comprise gas outlet 1, cover body 2 and base plate 3, cover body top, for the gas outlet 1 for connecing dust catcher, also comprises baffle plate 4, cover body lower end 21 is connected with intilted baffle plate 4, horizonal base plate 3 is by baffle plate 4 lower end closed, and baffle plate 4 is 135 degree with the angle that base plate 3 forms, and suction port 5 is intensive being uniformly distributed on baffle plate 4, suction port 5 is rectangular through holes, cover body lower end 21 is rectangle, and base plate 3 is also rectangle, and Area Ratio cover body lower end 21 areas of base plate 3 are smaller.
Start dust catcher, dust catcher siphons away air in cover body, forms negative pressure in cover body, and the band dust air of cover body below is inhaled into from suction port.Because only being positioned at the cover body lower end, suction port namely covers a mouthful surrounding, the base plate that cover mouthful middle body is sealing, suction port is more concentrated, so the suction of suction port is larger, fully absorb after drawing in the past by the band dust air of cover mouthful below, reach the effect of fixed point dust suction.
Claims (6)
